Suillus grevillei s.l.

Idaho last year had a lot of Suillus grevillei s.l. under Tamarack
(Larix laricina).

Suillus luteus has a purplish/white annulus, not a golden yellow one.

I’m glad we heard of S. clintonianus, a darker cap member of that
group. Who knows… Both are Larix associates. S. clintonianus is a
pretty good name, widely accepted and in currency in recent literature
from Europe (Fungi Europaei, Munoz, 2005). The interpretations of some
authors seem to have been synonymized differently within grevillei.

Not sure if someone has compared these molecularly to the European
material, but Prof. Tom Bruns from UCB is the one who should probably
know best the current state of Suillus research.

Under comments for S. grevillei B/B/F includes this, “some authors consider the darker colored form to be a variety S. grevellei var. clintonianus, or a distinct species, S. clintonianus.” The ones pictured here look like a dark version of S. gravellei, a common Larch Bolete here in the eastern US; except maybe that the cap is not so viscid as what I find here. B/R/B mentions the appendiculate cap margin in the big bolete book.

I know neither of those two mushrooms…

grevillei versus clintonianus

If that is true than forget this index!
German mycologist Karasch found S.clintonianus together with S.grevillei in Mongolia under Larix kaempfferi and both are clearly different.

grevillei is the currently accepted name for the old clintonianus…

What about Suillus clintonianus??
